f19b8f7665 gl: store the list of contexts within gldisplay 
Removes the reliance on the allocation query to propogate GL contexts.

Allows thread safely getting a context for the a specific thread.

f153b9ee59 gl: Remove format info in glcolorconvert's transform_caps function instead of on every caller 
... and let glmixer actually transform the caps it is supposed to transform
instead of inventing new caps.

5dfa3c8009 Revert "videoaggregator: Create new caps from the video-info" 
This reverts commit 78215be0df.

because it broke glvideomixer with custom caps features.

3555c7bcd9 videoaggregator: Create new caps from the video-info 
In case the original caps were missing some optional fields like
interlace-mode. We assume default values for those everywhere,
but they can still cause negotiation to fail if a downstream element
expects the field to be there and at a specific value.

b4ee792fc2 videoaggregator: fix buffer selection when duration=-1 
If the src framerate and videoaggreator's output framerate were
different, then we were taking every single buffer that had duration=-1
as it came in regardless of the buffer's start time.  This caused the src
to possibly run at a different speed to the output frames.

4860e179fa gl: initial support for texture targets other than GL_TEXTURE_2D 
Make GstGLMemory hold the texture target (tex_target) the texture it represents
(tex_id) is bound to. Modify gst_gl_memory_wrapped_texture and
gst_gl_download_perform_with_data to take the texture target as an argument.

This change is needed to support wrapping textures created outside libgstgl,
which might be bound to a target other than GL_TEXTURE_2D. For example on OSX
textures coming from VideoToolbox have target GL_TEXTURE_RECTANGLE.

With this change we still keep (and sometimes imply) GL_TEXTURE_2D as the
target of textures created with libgstgl.

API: modify GstGLMemory
API: modify gst_gl_memory_wrapped_texture
API: gst_gl_download_perform_with_data

4527811b1f videoaggregator: If getting a timeout before having caps, just advance our position 
This can happen if this is a live pipeline and no source produced any buffer
and sent no caps until an output buffer should've been produced according to the
latency.

This fix is similar in spirit to commit be7034d1 by Sebastian for audiomixer.

38a06d0a33 videoaggregator: fix crash when receiving buffer without timestamps 
Unset out buffer in clip function when we unref the buffer to be
clipped, otherwise aggregator will continue to use the already-
freed buffer. Fixes crash when buffers without timestamps are
being fed to aggregator. Partly because aggregator ignores the
error flow return.

26d1a22e90 aggregator: Add a timeout parameter to ::aggregate()

e354149436 aggregator: make the src pad task drive the pipeline for live pipelines 
This removes the uses of GAsyncQueue and replaces it with explicit
GMutex, GCond and wakeup count which is used for the non-live case.

For live pipelines, the aggregator waits on the clock until either
data arrives on all sink pads or the expected output buffer time
arrives plus the timeout/latency at which time, the subclass
produces a buffer.
